Abstract

Phase plane analysis is a standard analytical technique in nonlinear dynamics that has only recently been applied to unresolved issues concerning the initiation and maintenance of cardiac fibrillation, as well as the tissue response to strong stimuli. Using this method, we can localize phase singularities and filaments and quantify spatial and temporal heterogeneities associated with the cardiac cycle.
